NAME
       fsadm — utility to resize or check filesystem on a device

SYNOPSIS
       fsadm [options] check device

       fsadm [options] resize device [new_size[BKMGTEP]]


DESCRIPTION
       fsadm  utility checks or resizes the filesystem on a device.  It tries to use the same API
       for ext2, ext3, ext4, ReiserFS and XFS filesystem.

OPTIONS
       -e, --ext-offline
              Unmount ext2/ext3/ext4 filesystem before doing resize.

       -f, --force
              Bypass some sanity checks.

       -h, --help
              Display the help text.

       -n, --dry-run
              Print commands without running them.

       -v, --verbose
              Be more verbose.

       -y, --yes
              Answer "yes" at any prompts.

       new_size
              Absolute number of filesystem blocks to be in the filesystem, or an  absolute  size
              using  a suffix (in powers of 1024).  If new_size is not supplied, the whole device
              is used.


DIAGNOSTICS
       On successful completion, the status code is 0.  A status code of 2 indicates  the  opera‐
       tion was interrupted by the user.  A status code of 3 indicates the requested check opera‐
       tion could not be performed because the filesystem is mounted  and  does  not  support  an
       online fsck(8).  A status code of 1 is used for other failures.


EXAMPLES
       Resize  the  filesystem on logical volume /dev/vg/test to 1000 megabytes.  If /dev/vg/test
       contains ext2/ext3/ext4 filesystem it will be unmounted prior the resize.  All [y/n] ques‐
       tions will be answered 'y'.

       fsadm -e -y resize /dev/vg/test 1000M

ENVIRONMENT VARIABLES
       TMPDIR The temporary directory name for mount points. Defaults to "/tmp".

       DM_DEV_DIR
              The device directory name.  Defaults to "/dev" and must be an absolute path.
